Letters Patent No. 92,1-63, dated July 6, 1869.

IMPROVEMENT IN SAFETY-ATTACHNIENTS FOR BREAST-PINS.

y The Schedule referred to iu these Letters Patent and making part ofthe same.

panying drawings, forming part ot' this specification.

This invention relates to a new andusetul improvement in pins forfastening shawls, diapers, and articles of clothing, pocket-books,reticules, jewelry, and for all other purposes to which a safety-pin isapplicable.

The invention consists in the combination ot' a slid.- .ing bolt withthe xed tube and the slotted rotary tube, whereby they are lockedtogether, and prevented from beingr turned to release the point of the'pin whenv in use, as will be hereinafter more fully described.

In the accompanying plate ot'drawings-- v Figure 1 represents alongitudinal side View of a shawl or safety-pin, constructed accordingto my invention.

Figure 2 is 'a magnified sectional w'ew ot' the same, showing moreplainly the construction ofthe tubes.

Similar letters ot' reference indicate corresponding parts.

A represents the 'back or support ot' the piu, and of thefastening-device.

B O are end pieces'at-tached to the back, `A which stand at, or nearlyat right angles' therewith.

I) is the pin proper. s

To the end B, thel pin D, is hinged, as seen at e.

The fastening-device: is attached to the end C.

rllhis consists ot' an outer tube, E, which is soldered or fixed fast tothe end C.

In this tube there is a longitudinal slot for admitting the point ofthepin. A screw-thread is cutin the outer cud oi'this tube, E, as seen inthe drawing, iig. 2.

J represents the inner tube, which is provided with a screw-thread onits outside, so that it screws into F, as seen in tig. 2. y.

On its outer end there is a milled disk, g, by which the tube is turned.

Onits inner end there is a flange or collar, h, to prevent its beingdrawn ont or from the tube F.

Thistubeis `also slotted longitudinallyv for admitting the point ofthepin D. There isaslight longitudinal movement allowed to this inner tube,which is limited by the disk gand collar h, and it is so placed inthe'outer tube F, that by giving the tube a partial turn to the left,the collar It will come in contact with the end ot' the tube F, when themovement will stop. the slots in both the tubes will register orcorrespond, so that the pin D can be dropped down into the inner tube.

- v Now, by turning the inner tube a part of a revolution to the right,its slot passes down into the outer tube, the milled disk g is broughtin contact with the outer end of' the tube F, and secured thereby thesliding bolt b, as shown in red color in fig. 2.

This bolt is attached to the side of the tube F, and when it is thrownout, its free end ts into. a recess formed in the under side of themilled disk g,'aud thereby rmly locks the tubes JJ together, to preventtheir turning. By this means thepoint of the pin is securely held inIposition, and all danger of its being causually displaced and lost, .isavoided.

It will thus be seen, that by this simple and inexpensive arrangement, along-sought for article is found, the use of which, for securing, notonly articles of wearing-apparel, but articles ot' more value, aspocketbooks, portmonnaies, jewelry, &c., may be extended almostindefinitely. l y

Having thus described my invention,

VVha-t I claim as new, and desire to secure by Letters Patent, is f Thecombination of the sliding bolt b with the milled disk g, slottedmovable tube J, and iixed tube 1*arxanged'as described, for the` purposeot' locking the tubes together, as herein described, for the purposespecified.

- The above specification ot' my invention signed by me, this 8th day ofDecember, 1868.

FREDERICK CATLIN.
